. MECHANISM FOR RELEASING SPACE-BARS OF-LINOTYPE-MACHINES.

SPEGIPICATION formingpart of Letters Patent No. 635,997, dated October 31 1899. Application filed February 18, 1898. Serial No. 705,996; (No niodel-l To all whom it mag concern: I.

Be it known thatI, FRANK CUTTRISSDOLBY, of Broadheath, in the county of Chester, England,-have invented certain new and useful Improvements in Mechanism for Releasing them down the delivery-chute into the as sembly-box. V

I Referring to the accompanying draw ngs, Figure 1 is afront-elevatioz' oi the top 01. the space-bar magazine to which the present in-' vention has been applied, and Fig. 2 is a plan corresponding therewith. Fig. 3 .is a perspective view of the releasing device. Fig. t is a perspective view of the eccentric shaft, on, which the delivering device pivots and by whichit is adjusted for bands of d'iiferent thicknesses.

K- is the space-bar magazine, and kthe 66"., livery-chute from it to the assembly box.

Z are the space-bars, hanging by their shoulders .2 from the top .rails k? of the magazine K,,down which they slide by gravity till the shoulders 24 of the leading one bear against the releasing device, comprising the areshapededges is of a pair of sectors It, held together by a bush 70 turning upon a shaft 75', the journals of'which are concentric with the said edges is and turn in hearings in lugs :37, projecting from the top rails '70 The bottom end of the first space-bar rests against ashoulder "7,2 The edge k of each sector 70 l asa-notchk in it large enough to receive a shoulder s fthe two notches w lug wlined with eachothen. 7c? is a connecting-rod made fast by having its top end bent around the bar 70 which ex-'- tends from 'one sector It to theother, and by" by the depression .the shaft may. be inserted e'ndwise to its place. The bush k l fits. that eccentric. winch-handle fast upon the front end of the" its opposite endtoa key-lever, snot shown in the figures and by which the sai rod is raised the back of its outerend may automatically zoo each time a space-bar Z is to be taken from themaga zine K.) v

76 is a returning-spring pulling on the pair of sectors k from a fixed point on the magazine K. j v l s is a pin passed through the extensions 7:?" and an arcual slot is, in each sector-J11" to limit their motion. The sector edges is are concentric with the shaft. k and standjclose up to the 'openside of the magazine K. The

' notches 7:? are -so positioned in those edges that'so-longas the-rod k is not raised they stand lower than the shoulders -e -of the leading space-bar Z'. When thesaid rodis raised of its key-lever against the pull of the spring t the said notches first standopposite the said shoulders s, which then" slidei'nto them and then lift the spacebar clear of theshoulder 7 0". When the rod is is pulled down, the sectors k" are returned into the position villustrated'in the figures, as much of the edges 70 as then stand above the notches 70' holding backthe remaining spacebars',.while"the one whose shoulders were held by the said sectors drops down the chute To. It is obviousthat the notches 10 may not be larger than su-flices' to receive one pair of shoulders s at once and that consequently any pair of sectors notched and mounted as above described can deal only with space-bars of a given size and hanin g shoulders z of a certain thickness; 1

One' object of the present invention is to make thesectors capable of dealing with space-bars differing in the thickness of their shoulders '2 and it consists in interposing an eccentric portion of the shaft 70 between its journal and the bush 70 by which the edges It can be moved away from the magazine K, so as toallow the thicker shoulders .6 of stronger space-b'arsto be engaged by the notches k [k is an enlargement of the shaft It? circular in transverse section and eccentric to the two ends or journals of the shafl' which are concentric, but ot different sizes, so that 7c is a shaft k". It is resilient, so thata studla on front of the magazine K to hold thefiector i '1, engage 1n one of a series of holes 70 m tne edgesk at'their desired distance from the ciprocating. motion of the bush k upon the shaft it 1 The eccentric; enlargement k may be a.-
